The Logic Tape Delay....

Has some secret settings (as I'm sure some of you are aware) if you flip to the controls view..
One being 'distortion level' (gotta love that), the other is 'mix' which is kind of handy too.
rock on.

Cool!

Grrrrr Logic Pro won't update & What is up with my Tape Delay!!!!!

Right, i'm finding posting on this Forum intensely annoying already!!!
Anyway, can anyone tell me why when i try and update from Logic Pro 7.1 to 7.1.1 it won't let me do it? .....i download it....unstuff it .....and when i click to launch it's says it doesn't recognizea valid version of Logic Pro....yet updating to 7.1 was no problem.
Also, my Tape Delay will not delay consistently ....as the song position indicator passes a region with a tape delay insert ....there's no delay ...then suddenly it kicks in ...out of time/sync with the rest of the song .....it's driving me up the ******* wall!
no seems to have the same problem .....surely its not processing power although have realised that Apple did not make Logic to run on a normal or dual G4 which i'm currently running

the other thing re your upgrade problem is: what exactly is the error message? is it totally telling you that it cannot find a logic to upgrade, period? or is it saying that it has found a more recent version already installed? if the latter, you can ignore the error message and just go ahead and install.. the error message is bogus.
if not.. then I'm not sure what to suggest. all I know is that the app has to be left as is, and where it is, not even so much as put inside a little folder within the apps folder, which some people do when organising their apps.
I had this with a friend who was freaking out at the updater not working.. turns out he'd renamed the app 'Logic Pro 7.1', as he was accustomed to adding the version number to app icons since back on OS9. changed it back to Logic Pro and it went fine.
another thing to do is tr repairing your permissions.. which I presume you have been doing religiously after every software install like a good UNIX boy?

Tape delay gets cut off in the middle of a project

I'm working on a multichannel 24bit, 48kHz audio project in Soundtrack Pro version 1.1.
I'm using WAVs as source material.
One of the audiotracks contains a short sample of 1 second, that has a Tape Delay effect on it with the feedback on 55%, so it keeps repeating for about a minute. At least, that's what is should do.
The problem is that it gets cut off after around 15 seconds.
This does not happen when I solo the track or some of the tracks.
I've converted the 24bit, 48kHZ source WAVs to 24bit & 16bit AIFFs, but this doesn't make a difference.
I found a work around, by solo exporting & importing the track with the delay on it, but this is not how it should be.
Has anyone had similar problems and maybe found a solution?
Thanks.
G5 Dual 1.8Ghz Mac OS X (10.4.9)

For everybody who has the same problem: I found a solution.
Soundtrack appears to end an effect abruptly after around 15 seconds when there are no new clips on the timeline in that track.
The solution is adding 'silent clips' in those tracks every 10 or 15 seconds for as long as the effect has to continue. Not very elegant, but it works.

IDELAY tap delay across PVT?

Hello,
I have a design wherein the input data signal goes into the IBUF which drives an IDelay Block. I believe that tap delay value remains same across all PVTs, but the timing data obtained for different timing corners are not the same.
These are the results I obtained:
Datapath considered for timing analysis : IO Pad => IBUF => IDELAY==> D-input of ILOGIC FlipFlop
Experiment 1 : config_time_cornes -corner Slow -delay_type max_min
config_time_corners -corner Fast -delay_type none
Timing report : attached file : slow.png
Experiment 2 : config_time_corners -corner Fast -delay_type max_min
config_time_corners -corner Slow -delay_type none
Timing report: attached file : fast.png
I see the logic-delay of IBUF is different in these two cases, which is expected as i- changes with PVT.
However, the logic-delay of IDELAY block is changing as well:
0.331ns at fast process corner
0.666ns at slow process corner
Is this expected? If yes, how is tap delay assumed to remain same across all PVTs?
Also, i ran some iterations wherein I changed tap values and found the difference between delayed signals (tap-delay) at different process corners and I found that to be different too.
Could anyone explain this?
Any help will be appreciated
Thanks!

The calibration process does not take into account the exact values, but tries to calibrate by increasing/decreaasing these tap values such that the data is at the centre of the eye
Sorry, but that's not true...
Don't confuse the calibration process of the IDELAY (which is done internally using the IDELAYCTRL and sets the delay of each tap), and any user implemented dynamic calibration process that is trying to find the center of a data eye by adjusting the number of taps.
The delay taps in the IDELAY are calibrated to be fixed values. The average value of an individual tap is Trefclk/64, however there is some variation from tap to tap - notably, the first tap is larger than the rest.
The calibration done by the IDELAYCTRL calibrates a string of 64 elements, so that the sum of the 64 elements is one complete period of REFCLK. The calibration information obtained for these 64 element is used for the 32 elements in each IDELAY/ODELAY. If all the delay elements were identical, then that would result in the perfect tREFCLK/64 for each element, but they aren't perfectly identical - due to a number of internal factors, the delay elements are slightly different.
But, a given element will always be the same value across process voltage and temperature (PVT). So, if tap0 measures as 64ps, it will be 64ps across all PVT; tap1 may be a different value, but it will be that value across PVT.
There is a white paper that describes this effect (and others) for the Virtex-4 (which was similar to V5, V6 and the 7 series - but not UltraScale) here.
The static timing analysis tools know about the variation from tap to tap, so the results you get out of trce or Vivado static timing analysis will be exact; these should always be your final verification for "tweaking" the number of taps you want for static phase shifting of an interface.

Backup many tar files in the same tape

hi all
i have many small geoframe projects of size,,around 3,,,5 GB but the lower tape contain 24 GB availble space..
===> I WOULD BACKUP ALL THE SMALL PROJECTS UNDER THE SAME TAPE...
for example i have three project (proj1,proj2,proj3)
the problem is when i write these line for backuo these projects together then the tape is rewind even i use 0n option!!!!! :
$ mt -f /dev/rmt/0 rewind
$tar cvf /dev/rmt/0n proj1
$mt -f /dev/rmt/0 rewind
$mt /dev/rmt/0n fsf 1
$tar /dev/rmt/0n proj2
$mt -f /dev/rmt/0 rewind
$mt /dev/rmt/0n fsf 2
$tar /dev/rmt/0n proj3
===> logically, i should find the 3 project inside the tape (proj1,proj2 and proj3),,,but i always find the latest single project when i use the tar command for list the content of the tape:
$tar tvf /dev/rmt/0n
proj3
if someone know what's wrong whith this operation please don't hesitate to give me the solution
thanks in advance

Before running the tar, run 'mt -f <device> status' You should see that for later runs, your tape is not on file 0/block 0
Also, you're doing it the complex way. Don't rewind/forward between each one. Just always use the no-rewind device and leave the tape in place.
mt -f <tape> rewind
tar cf <tape> proj1
mt -f <tape> status # verify not at beginning of tape
tar cf <tape> proj2
[etc]
If you use the rewind device, then when you run 'status', you'll see the tape is at the beginning.
Try again, but this time show the status just before running the final tar to tape, and show the status just before gathering the contents of the tape.

The logic of iCloud settings ??

The logic of iCloud settings ??
I don't understand how iCloud settings are organized. Can someone please explain? I indicate the confusing aspects below.
Tapping iCloud brings up a page titled ‘iCloud' and which is a mix of Apple apps and services. But it’s not clear whether these have anything to do with ’Storage’. If so, I would expect the storage used by each app or service to be indicated.
Tapping Storage brings up:
Tapping Manage Storage there brings up a mix of Apple and 3rd party apps under the heading “Documents and Data”. But the total is only 110.1 MB, only a part of the 3.3 GB supposedly used.
Tapping iCloud Drive brings up a long mix of Apple and 3rd-party apps, with no indication of storage used.
And there is duplication with the earlier lists:
Safari was also in the first list, above -- why is that?
Pages and Keynote are also in the second list above -- why??
Numbers is only below but not above.
Why are some 3rd party apps listed here and some on the prior sheet?
And why are these -- a subset of my apps -- the only ones that show in the list? Shouldn’t Apple provide an iCloud storage option for all apps as a basic iOS service?
Tapping Backup brings up:
which has no indication of how much storage Backup is using.
Finally, the names and descriptions Apple gives for iCloud, iCloud Drive, and Storage aren’t much help:
The iCloud Drive FAQ at https://support.apple.com/en-us/HT201104 says: "With iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images, and any other kind of document in iCloud."
iCloud: What is iCloud? at https://support.apple.com/kb/PH2608?locale=en_US&viewlocale=en_US says: "iCloud gives you access to your music, photos, contacts, calendars, documents, and more from your Mac, iPhone, iPad, iPod touch, and Windows computer. iCloud stores your content and automatically keeps it up to date on all your devices."
Are iCloud, iCloud Drive, and Storage all the same thing? Why different names?

> iCloud is a collection of online services …
Thanks -- that's a clearer statement than what I've seen from Apple.
But I'm still confused by the organization of the settings. For starters:
What is the purpose of the first list? Some items there are services, others are apps.
Given that 'storage' includes Backup, why is Backup not included in iOS settings for Manage Storage?
Why do certain apps appear in multiple lists:
Safari is on both the iCloud and iCloud Drive lists on iOS but only on the iCloud list in MacOS.
Pages is on Manage Storage and iCloud Drive on both iOS and MacOS.
Same for Keynote.
(Numbers is only on iCloud Drive on both iOS and MacOS.)

IDELAY : Tap delay control using Ref_frequency

Hello,
I am trying to understand the IDELAY modules and I've read quite a few discussions on this forum regarding the same.
My doubt is the following:
I am using Kintex-7, with speed grade -2 and the data sheet states that I must get an average delay of 52ps (Tap delay) when I set the reference frequency to 300Mhz.
I tried driving two IDelay blocks with tap values 0 and 1 with the same signal(data_in). Ideally, the output must be two signals separated by 52ps; This is exactly what I see in the post-route FUNCTIONAL simulation.
However, when I run the post route TIMING simulation, the difference is 64ps and not 52ps.
Also, I probed the DATAIN pin of the two IDelay blocks and I see the signals at the input of both the IDELAY blocks, arrive at the same time. This means the routing delay is not causing the extra (65-52)ps of delay.
Could anyone please explain this?
Thanks!

Tapped delay line structure

If I wish to emulate a wireless multi-path channel, is there a way I can bring in the tapped delay line filter structure into my LV code ? I mean, would I be able to get accurate delays, say in the order of ns for my taps ? Also, how do I model the delays ?I've been searching for help on this subject but haven't been able to find much.

If you know your filter specifications (lower/upper passband/stopband) then you can use the "Digital FIR Filter" vi to filter your channel. If you know the coefficients of the desired filter, then you can use the "FIR Filter" vi. One way you can create delay is to use the "Continuous Convolution (FIR)" vi to convolve your waveform with a shifted Kronecker delta. You can make this delay in the order of ns if the sampling frequency of the simulated channel is high enough. Have you looked at LabVIEW examples that use filtering? Check out the example "FIR Filtering and Response.vi" in the NI Example Finder.

How do I get the logic board serialized?

I had the logic board replaced a year ago in my iMac. Ive been having some problems sharing maps with my other mobile devices. Someone suggested to check to see if the logic board is serialized. Anyone know how to do this?

Go to About this Mac in the Apple menu.
Tap the version number twice. If you see a serial number, it has been set. If not, then take it to an Apple Store or Service center and have them fix it.

I replaced the logic board- now nothing...

This is really a continuation of this thread:
http://discussions.apple.com/thread.jspa?threadID=2542941&tstart=0
It is now the end of September and I have been unable to use my Power Mac since early August/Late July.
to recap: I replaced my logic board, but then the machine wouldn't turn on. The power button wouldn't stay illuminated and the screen remained blank but I could hear the whirring of fans and maybe drives.
I brought the tower to the Genius bar where they opened it up and promptly told me my CPU was fried.
Fortunately it was still under warrantee And OWC said send it on back and we'll see what we can do.
Turns out the Newer Technologies 2.0 ghz CPU has been discontinued. The folks at OWC were trying to find out if they could get it rebuilt or just what they could offer me to honor the warrntee on a dicontinued item.
So we agreed to a dual 1.6 CPU that I received in the mail Tuesday and installed last night.
Unfortunately the same thing happened. I hear it try to start but there's no chime and the on/off button only remains illuminated as long as I hold it in.
Could it be a bad logic board?
because the CPU is an aftermarket product, it comes with firmware to be installed. When I replaced the logic board, did it maybe not recognize the CPU? (I'm grabbing at straws here.)
I will probably bring it in to the Genius bar again and have them look at it, but I just thought I would try here first in case anyone might recognize the symptoms.
thanks.

the heatsink came out first, and then the card with the processor.
The processor chip and card are one assembly called a daughter card.
I just don't know how to go about re-installing it. Is there a temporary fix short of solder?
It's not solder.
The OEM CPU and heat sink have thermal tape that is hard to break when cold.
When hot, the heat sink is easily removed.
Simply reinstall the CPU daughter card, put a bit of thermal compound on the old tape, and fasten the heat sink.
This will work well enough to run the firmware patch.
For more thorough instruction, I wrote it up here:
http://www.jcsenterprises.com/Japamacs_Page/Blog/9AE7FE0E-0CF2-4A7C-8003-489B282 582BC.html
I couldn't locate a voltmeter that would work at this level.
Any electronics store will have a volt ohm meter; Radioshack, Fry's, etc.
They are inexpensive.

Replacement of the logic board of mbp 15" 2010 mid

Recently, I replaced the logic board of my mbp 15" (2010 mid ver.).
By the way, since then, I can't recover my mbp via internet recovery.
I found a message "Apple can't recognize my computer ~~" blah blah~.
Is this ordinary ?
Anyway, I found a software update (maybe EFI Firmware) that makes possible the internet recovery.
(http://support.apple.com/kb/HT4904?viewlocale=en_US)
But, the software is not installed.
It says my system doesn't support the update.
Is this ordinary ?
After the replacement, I have observed several weird phenomena even though I can't say them clearly.
very long delay of app launch.. or finally fail to lanuch an app. fail to install Mavericks.. and so on.
But, AHT doesn't find any hardware error.

Here.. the problem is... I can't do clean install Mavericks.
I have tried to install Mavericks cleanly several times, but I failed.
In the last step of the installation (usually user configuration step), my mbp stops. not working.
I don't know why..
My current OS is mountain lion.. the installation of this was also very tough work.
In the middle of the installation, mbp suddenly stops (so I reboot 2~3 times by force).
I guess all problems are caused by the replacement of logic board.
But, as I mentioned before, the result of AHT is there is no hardware problem.
Can an engineer of apple repair center find out any hardware failure even if the result of AHT is no hardware error ?

Finding of the Logical and Physical filename,Logical and Physical Path

Hello All
Where and how can I find the below details in an SAP server
Logical filename:
Physical filename:
Logical path:
Physical path:
Regards
Kalyani

hi
Physical file is what you see from the OS level.
Logical file is what ABAP code can call certain functions to read/write.
Transaction FILE would link them together. Typically the logical path ends with "<FILENAME>", and the logical file refers to the logical path.
To extract the physical path from the logical path name
DATA: lf_mandt TYPE sy-mandt,
lf_opsys TYPE sy-opsys.
lf_mandt = sy-mandt.
lf_opsys = sy-opsys.
To extract the physical path from the logical path name
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
client = lf_mandt
logical_filename = p_unix
operating_system = lf_opsys
IMPORTING
file_name = gwa_input
EXCEPTIONS
file_not_found = 1
OTHERS = 2.
IF sy-subrc EQ 0.
Concatenating the physical path and the input unix file name
CONCATENATE gwa_input p_file INTO gf_file .
ENDIF.
You need to tak ehelp of ABAPer for this

LSMW: Error concerning the logical path in Specify Files step

Hi,
I am trying on an ECC 6.0 EHP6 system to upload (open) POs from an existing SAP ERP system. Since I faced some complications in batch input recording method, I decided to go with the standard batch/direct input method.
I selected object 0085 (Purchase Order) and method 0001 (Purchase Order). The program that is used is RM06EEI0. I followed all the usual steps, but in the "Specify Files" step I get the message:
'****.lsmw.conv' does not exist; edit the logical path using transaction FILE
Being aware of both the FILE and SF01 transactions, I created the logical path and file (through the FILE transaction). However, after the modification, I get the message:
Logical file '****' is not assigned to physical file '****.lsmw.conv'
There is also the related SAP Note 753511 (Logical and physical path and file name in transaction LSMW) that refers to this case.

Hi,
Click on specify file radio button>Legacy data-on the PC Front end
where input file location like C:\mydocument\desktop\test.txt
and give input in Name field: mydocument
in delimiter section > select Tabular
File structure section> tick on Field order matches source structure definition
File type: Record end marker(Text file)
then press enter key and other steps as same.
Second thing you said that you have used Batch input recording
after creation and recording finish , scroll the page below on recording and put a cursor unwanted field and remove unwanted input field.
I hope your problem will resolve. you can find the steps pdf on Google search try now.
Thanks
